About radiography films: Radiography films are primarily made up of two things; 1. Base 2. Emulsion Base: Base is a transparent, flexible blue tinted object, usually made from a clear and flexible plastic such as cellulose acetate. It provides physical support to emulsion and does not participate in the image-forming process. It is not sensitive to radiation, nor can it record an image. Emulsion: Emulsion consists of gelatin which consists of….
Radiography testing (RT) is one of the most widely used non destructive test (NDT) method. With the help of this method we can detect hidden flaws or discontinuities present in welds such as cracks, porosity & blow holes, slag, flux or oxide inclusions, lack of fusion, incomplete penetration, Mismatch and tungsten inclusion etc. Short wavelength electromagnetic radiations such as X-rays or Gamma rays (γ) are used for Radiography testing. Both….
